Motion
Event that involves a change in position or location of something.

Type of motion
-Uniform motion = Constant speed in a straight line.
-Accelerated motion = Motion that is changing in direction or speed.
-Circular motion = Speed is constant but the direction of motion is changing continuously.

Vector and scalar quantities.
Vector- A quantity that has both magnitude and direction is called vector quantity.
Scalar- A quantity that has only magnitude or direction is called scalar quantity.


Scalar
-Magnitude or direction only
-Independent of direction

Vector
-Both magnitude and direction
-length represent megnitude.
-Arrows shows direction.

Speed = direction* time

Distance = အစအဆံုး သြားခဲ့တဲ့ ခရီး
Displacement = အစထြက္တဲ့ အမွတ္နဲ ့ေနာက္ဆံုးေရာက္ခဲ့တဲ့ ေနရာအကြာအေ၀း။
